<itemvalue="Creates a widget that scales its child along the 2D plane. The `scaleX` argument provides the scalar by which to multiply the `x` axis, and the `scaleY` argument provides the scalar by which to multiply the `y` axis. Either may be omitted, in which case that axis defaults to 1.0. For convenience, to scale the child uniformly, instead of providing `scaleX` and `scaleY`, the `scale` parameter may be used. At least one of `scale`, `scaleX`, and `scaleY` must be non-null. If `scale` is provided, the other two must be null; similarly, if it is not provided, one of the other two must be provided. The [alignment] controls the origin of the scale; by default, this is the center of the box. {@tool snippet} This example shrinks an orange box containing text such that each dimension is half the size it would otherwise be."/>
